Home / Heat recovery
Whole-house heat recovery.
Horizontal and vertical MVHR, with automatic summer bypass, frost protection and remote commissioning.
How it works
Two airstreams, one counterflow exchanger.
Stale air leaving the building passes heat to fresh air coming in, controlling condensation and pollution in residential properties. Boost can be triggered from a light switch, remote humidistat, PIR, thermostat or pull cord.
- Trickle, boost and purge speeds set at installation
- Run-time and power-outage counters, viewable via QR code
- Optional holiday mode and 0-10V connections for BMS, CO2 detector or home automation
Horizontal range.
Vertical range.
